Abstract
In this study the nonlinear optical properties of Eosin-B dye nanoparticles were studied using the scanning-fluorescence spectrophotometer and fluorometer method. The nano water droplet in the oil medium is prepared by a combination of hexane and surfactant water, which is painted inside the drop by Eosin-B. The droplet size was studied on a nonlinear refractive index using a 532 nm laser with a scanning power of 80 mW. The results show that the surface effects on the nano-droplets cause the droplets to have a larger nonlinear refractive index. This change was due to a decrease in the accumulation of dyes inside the droplet as well as a decrease in the polarity of the drop solvent relative to the water solvent.
